Its color is cheerful and it's longer than the original cable. It works well with my iPhone 4s. I plan to buy another one; one for my office and the other for my home. I'm still waiting for the delivery of the second cable.
Finally I found it ! with 200cm of cable you can go anywhere! of course it will be a little slower during the recharge but it really worth ! I got two: one green and one red and they're both perfect ! i recommend this to everyone !
